- There were two friends who were out walking their dogs when one of them stepped on a bun and heard how it cracked, says police spokesman Patric Fors.

When the woman picked up the bun, she noticed that it had been fitted with metal parts.

- She perceives that it is about razor blades and that there were a total of 10-15 buns on the site.

This is the latest in a series of similar acts that have occurred in Malmö since last autumn.

As recently as just over a week ago, another dog owner reported that he had been forced to take his dog to the vet after the animal ingested a pair of metal buns at a green area.
